Objective: To isolate and make a comparative study of marine sediments actinomycetes from Pulicat estuary, Muttukadu estuary and Ennore estuary, TamilNadu, India. Methods: A unique selective enrichment procedure has resulted in the isolation and identification a total of 304 actinomycetes colonies which were isolated from different stations of marine soil sediments in Pulicat estuary, Muttukadu estuary and Ennore estuary, TamilNadu, India. Results: Among them, 277 isolates were morphologically distinct on the basis of spore mass colour, aerial and substrate mycelium formation and production of diffusible pigment. The majority (60%; 162 isolates) were assigned to the genus Streptomyces. (35%; 104 isolates) were assigned to the genus Actinopolyspora, (5%; 11 isolates) were assigned to the genus Nocardiodes. Conclusions: The present study concluded that the physiological characteristics of actinomycetes Streptomyces, Actinopolyspora and Nocardiodes varied by available nutrients in the medium and the physical conditions.

Traditional medicine system of India comprised varieties of plants which are playing a significant role in curing diseases from ancient times. Among them, Enicostemma littorale blume (E. littorale) a perennial herb of the family Gentianaceae is cosmopolitan in occurrence in India. The bittery natured plant acts as a laxative, helps in curing fever, rheumatism, skin diseases, abdominal disorders, snake bite, obesity and helps to regulate blood sugar levels. The plant constituents have been reported for possessing antimicrobial, antioxidant, antiulcer, antiinflammatory, hypolipidaemic, hepatoprotective and hypoglycemic properties. This review provides a bird’s eye view about geographical distribution, physicochemical parameters, phytoconstituents and pharmacological properties of E. littorale.

BACKGROUND AND OBJECTIVES: Sensorineural hearing loss (SNHL) in children is associated with neurocognitive morbidity. The cause of SNHL is a loss of hair cells in the organ of Corti. There are currently no reparative treatments for SNHL. Numerous studies suggest that cord blood mononuclear cells (human umbilical cord blood, hUCB) allow at least partial restoration of SNHL by enabling repair of a damaged organ of Corti. Our objective is to determine if hUCB is a safe treatment for moderate to severe acquired SNHL in children. SUBJECTS AND METHODS: Eleven children aged 6 months to 6 years with moderate to severe acquired SNHL were treated with intravenous autologous hUCB. The cell dose ranged from 8 to 30 million cells/kg body weight. Safety was assessed by measuring systemic hemodynamics during hUCB infusion. Infusion-related toxicity was evaluated by measuring neurologic, hepatic, renal and pulmonary function before and after infusion. Auditory function, auditory verbal language assessments and MRI with diffusion tensor imaging (DTI) were obtained before and after treatment. RESULTS: All patients survived, and there were no adverse events. No infusionrelated changes in hemodynamics occurred. No infusion-related toxicity was recorded. Five subjects experienced a reduction in auditory brainstem response (ABR) thresholds. Four of those 5 subjects also experienced an improvement in cochlear nerve latencies. Comparison of MRI with DTI sequences obtained before and after treatment revealed increased fractional anisotropy in the primary auditory cortex in three of five subjects with reduced ABR thresholds. Statistically significant (p < 0.05) reductions in ABR thresholds were identified. CONCLUSIONS: TIntravenous hUCB is feasible and safe in children with SNHL.

Background: and Purpose In real-world practice, the benefit of mechanical thrombectomy (MT) is uncertain in stroke patients with very favorable or poor prognostic profiles at baseline. We studied the effectiveness of MT versus medical treatment stratifying by different baseline prognostic factors. Methods Retrospective analysis of 2,588 patients with an ischemic stroke due to large vessel occlusion nested in the population-based registry of stroke code activations in Catalonia from January 2017 to June 2019. The effect of MT on good functional outcome (modified Rankin Score ≤2) and survival at 3 months was studied using inverse probability of treatment weighting (IPTW) analysis in three pre-defined baseline prognostic groups: poor (if pre-stroke disability, age >85 years, National Institutes of Health Stroke Scale [NIHSS] >25, time from onset >6 hours, Alberta Stroke Program Early CT Score <6, proximal vertebrobasilar occlusion, supratherapeutic international normalized ratio >3), good (if NIHSS <6 or distal occlusion, in the absence of poor prognostic factors), or reference (not meeting other groups’ criteria). Results:  Patients receiving MT (n=1,996, 77%) were younger, had less pre-stroke disability, and received systemic thrombolysis less frequently. These differences were balanced after the IPTW stratified by prognosis. MT was associated with good functional outcome in the reference (odds ratio [OR], 2.9; 95% confidence interval [CI], 2.0 to 4.4), and especially in the poor baseline prognostic stratum (OR, 3.9; 95% CI, 2.6 to 5.9), but not in the good prognostic stratum. MT was associated with survival only in the poor prognostic stratum (OR, 2.6; 95% CI, 2.0 to 3.3). Conclusions  Despite their worse overall outcomes, the impact of thrombectomy over medical management was more substantial in patients with poorer baseline prognostic factors than patients with good prognostic factors.
